VPLS Flat Manual Triangle

Note before: If using "address-family l2vpn vpls" between IOS and IOS-XR or IOS and Junos, on the IOS side "neighbor x.x.x.x prefix-length-size 2" must be configured because IOS-XR and Junos interpret the NLRI prefix length field as 2 bytes but IOS by default encodes the NLRI length in the fist byte in bits format in the BGP Update message.

The 1941 test CPE has three interfaces each in a seperate VRF connected to each point of the VPLS triangle using a shared /24 so that pinging between interfaces is via the VPLS service.
